如果一个滚动，则链接两个 UITextView 一起滚动

Question

我有两个并排的文本视图，其中包含多行文本。

如何根据同时滚动其中一个来使它们一起滚动？

Answer 1

第一个

 @interface ViewController : UIViewController <UITextViewDelegate>

第二个使两个 textView 都延迟

  tv1.delegate = self  

  tv2.delegate = self

实施

-(void)scrollViewDidScroll:(UIScrollView *)inScrollView {

    self.tv1.contentOffset = inScrollView.contentOffset;

    self.tv2.contentOffset = inScrollView.contentOffset;

}

这是一个演示 txView

编辑

.h

#import <UIKit/UIKit.h>

    @interface ViewController : UIViewController <UITextViewDelegate>

    @property (weak, nonatomic) IBOutlet UITextView *tv1;
    @property (weak, nonatomic) IBOutlet UITextView *tv2;

    @end

.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.tv1.delegate = self;

     self.tv2.delegate = self;
}
- (void)scrollViewDidScroll:(UIScrollView *)inScrollView {

    self.tv1.contentOffset = inScrollView.contentOffset;

    self.tv2.contentOffset = inScrollView.contentOffset;

}
